Biphenyl Cyclobutenone Photoelectrocyclizations

The Journal of Organic Chemistry, 2021
In this work, we demonstrate that readily available conjugated bis-aryl cyclobutenones undergo photoelectrocyclization reactions to give the corresponding dihydrophenanthrene cyclobutanones when exposed to 350 nm light, TFA, and TMSCl. We have also found that cyclobutenone electrocyclizations and cycloreversions are in equilibrium.

The chemistry of biphenyl

Experientia, 1950
Das Biphenyl wurde mit Hilfe der Methode der «Molecular orbitals» studiert. Die Ergebnisse stimmen mit der praktischen Erfahrung uberein; es scheint aber, das auch sterische Wirkungen mitspielen. Es mus bestritten werden, das diep-Stellung die elektronisch wirksamere ist.

The Raman spectrum of biphenyl and biphenyl-d10

Spectrochimica Acta Part A: Molecular Spectroscopy, 1971
Abstract A set of polarized Raman spectra obtained from suitably oriented single crystals is presented together with depolarization ratio data for the lines from solution spectra. These measurements allow the symmetries of non-totally symmetric modes to be assigned for the first time from experiment alone.

Core Excitations of Biphenyl

The Journal of Physical Chemistry A, 2005
High-resolution C(1s) near-edge X-ray absorption and X-ray photoionization spectra of the free biphenyl molecule are presented and theoretically analyzed in order to allow an assignment of the observed spectral features. Finite lifetime broadening, a high density of vibrational states, and a strong overlap of contributions from chemically different ...

The polarized i.r. spectrum of biphenyl and biphenyl-d10

Spectrochimica Acta Part A: Molecular Spectroscopy, 1975
Abstract The i.r. spectra of biphenyl and biphenyl- d 10 in the range 80 to 3500 cm −1 have been measured polarized along three mutually perpendicular directions in the crystal; the c polarized spectra are reported here for the first time.

Analysis of polybrominated biphenyls

Journal of Chromatography A, 1977
High-performance liquid chromatography, gas chromatography-mass spectrometry, ultraviolet spectrometry and nuclear magnetic resonance spectrometry have been used to characterize the behaviour of a number of individual brominated biphenyls and to assess the composition of several mixtures of these compounds.
